These words, to which we have come in the ordinary course of our exposition, make an appropriate text for Easter Sunday. For their one theme is the joy which began upon that day, and was continued in increasing measure as the possession of Christ's servants after Pentecost. Our Lord promises that the momentary sadness and pain shall be turned into a swift and continual joy. He pledges His word for that, and bids us believe it on His bare word. He illustrates it by that tender and beautiful image which, in the pains and bliss of motherhood, finds an analogy for the pains and bliss of the disciples, inasmuch as, in both cases, pain leads directly to blessedness in which it is forgotten. And He crowns His great promises by explaining to us what is the deepest foundation of our truest gladness, 'I will see you again,' and by declaring that such a joy is independent of all foes and all externals, 'and your joy no man taketh from you.' There are, then, two or three aspects of the Christian life as a glad life which are set before us in these words, and to which I ask your attention. I. There is, first, the promise of a joy which is a transformed sorrow. 'Your sorrow shall be turned into joy,' not merely that the one emotion is substituted for the other, but that the one emotion, as it were, becomes the other. This can only mean that _that_, which was the cause of the one, reverses its action and becomes the cause of the opposite. Of course the historical and immediate fulfilment of these words lies in the double result of Christ's Cross upon His servants. For part of three dreary days it was the occasion of their sorrow, their panic, their despair; and then, all at once, when with a bound the mighty fact of the resurrection dawned upon them, that which had been the occasion for their deep grief, for their apparently hopeless despair, suddenly became the occasion for a rapture beyond their dreams, and a joy which would never pass. The Cross of Christ, which for some few hours was pain, and all but ruin, has ever since been the centre of the deepest gladness and confidence of a thousand generations.
